i think i know what you mean. there are 2 rails the bracket slides into. 1 in front and 1 in back. your saying when the top panel is mounted, these 2 rails are stiff in place. but when the top panel is off you can bend the rails outward a bit. so instead of sliding it in, you are putting it straight into the first/front rail then bending the back rail outward to push the bracket into place.
i did 2 more mods to my top panel. i cut out the grills in the front and back. its a soft plastic, so my dremel cut through it like butter. i also removed the grills from the side cut outs. i figure it was restricting air flow for no reason. they are in place by a thin strip or double sided tape. they are easy to peal off without bending or damaging them. i figure i can put them back if i ever need to.
these two mods allow for better airflow, i havent done any specific testing but when fans are at full speed i can definitely feel the air being pushed through the side vents a lot more.

i have come across a few reviews on youtube on the evolv and mastercase pro... i cant decide which one i want more. i figure i will probably get whatever one comes up on sale on slickdeals first.
the external design of the evolve in steel gives you that high quality (high price) apple look. which i really like. if its for your desk at work, or you live in architecturally modern home/office, this is the case you should get.
evolve con: bye bye blu ray burner, or hello big/bulky/ugly external 3.5 drive bay).
EDIT/UPDATE: from the hardwarecanucks review video i dont think the evolv will work for me. i dont think you could fit a h100i up top AND a water cooled GPU 120mm exhaust. not enough room?!?!
the mastercase pro 5 external, though not as nice (the front grill looks a bit boring), is nothing to shack a stick at. the internal customization seems to be better than the evolv (imo or for my needs). i have a h100i, and i like that i would be able to hide some of rad/fans above the mobo, rather then it dropping down in front of the mobo. i use noctua fans which are as ugly as you can get, so i would rather have them hidden.
Con for MC pro 5. i would only be able to fit 2 front intake fans. my current case gives me fan options on the side panel for my 3rd and optional 4th intake. 1) this ensures positive air flow pressure (more intake then exhaust) 2) i eventually want a nvme drive, and from reviews they perform better with a fan directly on them, they tend to thermal throttle (aka the side panel fan on my current case is perfect). these 2 cons could be eased by the simple fact of running the 2 intake fans at a higher speed, but that kinda sucks for daily use since my pc is in my bedroom connected to my tv (used like a HTPC).
i would really like to see both cases with a 240mm aio cpu cooler (up top) along with a gpu with an aio 120mm cooler (rear exhaust) to see how my current parts would look in each case. they look ok in my current setup, but i could see the potential of my current parts making certain cases look crowded.
current setup:
cooler master storm scout 2
h100i (with noctua rad fans)
295x2 GPU = 120mm rad built in (with noctua rad fan).
(3) noctua case fans (intake) (set on slow, fan speed curve set using asus fan control software)
TLDR; as i typed this, i think i realized i would go for the mastercase pro 5 first, but i would also be happy with the evolve if i got it at a good price.
